In vivo elemental analysis in occupational medicine.
本文讨论了源自核物理和原子物理的体内测量技术在职业医学中的应用，重点介绍了中子活化分析和X射线荧光技术用于测量镉和铅，并以镉的毒理学研究为例说明其价值。
The application of in vivo measurement techniques, derived from nuclear and atomic physics, to problems encountered in occupational medicine is discussed. The main techniques, neutron activation and X-ray fluorescence, are described, and their use for in vivo measurements of cadmium and lead is explored in some detail. The extension of these and other, related, techniques to the possible measurement of other elements of importance in occupational medicine is considered. The use of in vivo measurements as a tool for research into the toxicological effects of cadmium, associated with occupational exposure is taken as an example of the way in which in vivo elemental analysis can contribute to research in occupational medicine.
